Answer:Ultraviolet radiation has shorter wavelengths and higher energy than infrared radiation.
Explanation: Electromagnetic radiation radiations which have both electrical and magnetic properties,they can be transmitted through space or through a medium.
It includes Gamma radiation, infra-red, visible light, Ultraviolet radiation etc they occur with different wavelength, the lower the wavelength the higher the Energy dissipated per photon. According to their order of decreasing wavelength and increased energy they are classified as follows.
RADIO WAVE, MICRO WAVE, INFRA-RED, VISIBLE LIGHT, ULTRAVIOLET RAY, X-RAY, GAMMA RAYS.
Because the polar regions receive low-angle insolation.
Insolation is the amount of solar radiation received by a given area. The Sun is always low on the horizon. The low Sun angle makes the beam of solar radiation to travel a longer distance from upper troposphere to reach earth's surface as compared to when it is directly overhead. In this case, the radiations are scattered and reflected more by the atmosphere and spread over a larger area. Thus, the intensity of solar radiation is very less at polar regions than near the equatorial region. This is the reason of very cold climates at polar regions.

Answer:
1300.80988 Nm
730.79206 kgm²
Explanation:
m = Mass of ladder = 23.8 kg
g = Acceleration due to gravity = 9.81 m/s²
L = Length of ladder = 9.08 m
F = Applied force = 260 N
= Angular acceleration = 1.78 rad/s²
I = Moment of inertia
Weight is given by
The center of gravity of the ladder lies at the center of the ladder
Torque will be
The net torque acting on the ladder is 1300.80988 Nm
Torque is also given by
The moment of inertia of the ladder is 730.79206 kgm²
